Step-by-step explanation:
I assume they intersect at a right angle (90°).
then the intersection is a rectangle with one side being 12 m, and the diagonal being 13 m long.
the diagonal is the Hypotenuse (baseline) of a right-angled triangle with the length and the width of the rectangle as legs.
so, by using Pythagoras we have
diagonal² = length² + width²
13² = 12² + width²
169 = 144 + width²
25 = width²
width = 5 m
so, Oakdale Avenue is 5 m wide.
J/8: the quotient of two numbers is one over the other, or divide.
Answer:
The arithmetic average return would be 3.96%
Step-by-step explanation:
Given,
The returns in 5 years are,
-9.7%, -8.1%, 15%, 7.2%, and 15.4%
We know that,
Hence,
The arithmetic average return of the investment = 
= 3.96%
Answer:
4 x 1
Step-by-step explanation:
The dimensions of matrix id determined by it's no. of rows x no. of columns
Since this matrix has 4 rows and 1 column, hence 4 x 1
